Java on TI-89/92+?
Posted by Eric on 6 June 2001, 21:27 GMT

Well, we've got BASIC, assembly, and C so far, so why not Java? Stephan Effelsberg has undertaken the challenge to port the Waba Virtual Machine to TI calculators. He's released a very preliminary beta for the TI-89 and TI-92+. Development is still in progress, but it's already able to run nifty programs like Scribble. Check out Stephan's WabaVM page and let him know if you can help with the programming. Good luck!

You got that right! That IS sweet! I know a bit of Java. If I only had a TI-89/92+...

Kewl How about java script? Is it closs enough to java (like just a compiled version of the same code) that i can use it or am i out a luck?

Well, Javascript is kind of like Java. It just is not as powerful, and Java is in their own little applet thing, and Javascript is almost what I'd call an "HTML helper". Either way, they have a lot in common, so if you know one, learning the other shouldn't be hard.

Javascript != Java

Netscape named it Javascript to ride the Java hype. They're nothing alike.

In fact, Javascript is now called ECMAScript.

Java != Javascript at all!!

The post above summed it up well, but further... Java is entirely its own language, whereas Javascript (now ECMAScript) is very like C++ but for webpages. Java is "compiled" to something that can't actually be run on and computer natively, and therefore has to be emulated, on what they call a Virtual Machine. This makes it REALLY slow and inneffcent. I can't believe anyopne expects this to be usable on a CALCULATOR!

Java!!! Stuff changed so fast, Does the TI inc. knows about this?

Hmmm. This might actually get me to leanr to use JAVA in a non-webpage mode. . .

cool, maybe i'll pay more attention in java class. You see ti-89's and 92 promote good learning desires. Not much i can say about ti's other follies.

Ok, What IS Evil Dead 89? I've been wondering for about two months now.

Now we need java on the computer

I've always thought it was a bit of a disgrace that there is no java program section at ticalc.org, and I've promised myself that if I ever submit a computer program it will be in java. Unfortunately I haven't felt the need to write anything. Oh well.

Why doesn't someone make a practical virtual machine for the TI-89 and 92/92+? Like how about a VM that'll run assembly apps from TI 83+s, 85s, 86s, etc on an 89/92/92+? Hmm, now that I think about all of the possible assembly languages those calcs use..that could be difficult..but still.

The TI-83(+)(SE), TI-82, TI-85, and TI-86 use a Zilog80 processor - Meaning they use only one assembler language - Zilog80 assembler. The TI-89/92(+) have m68k processors.

So? Still why can't you make an emulator? There lots of such proggies on PC.

well, considdering most _computers_ have trouble emulating the calcs at much more than 200 percent, I doubt one of the calcs could do it very well.

pure speculation, but seem reasonable

I suppose, but on this comp, I can emulate a 92+ at about, oh say 650% during normal use with VTI.

So assuming your computer is somewhere around 1 GHz, even ignoring memory means that you need a 150 MHz chip to emulate these guys at full speed. Sorry, no go. Getting a vti-like program on a compaq Ipaq would be cool, though.

(anxiously typing in the hopes of running Mario and Diamonds for his 86 on his 89)Where would I find it?
